Description

  The present invention is a conveyor type freezing apparatus capable of continuously feeding a product such as food into a freezing device and taking out the product after freezing is completed. The present invention relates to a conveyor type freezing apparatus with a dew receiving device that prevents and maintains a sanitary environment.

  Conventionally, as one form of the refrigeration / refrigeration apparatus, a tunnel-type apparatus main body and a transport conveyor disposed in the apparatus main body are provided, and the object to be frozen / refrigerated conveyed by the transport conveyor is the apparatus main body. The apparatus main body comprises a tunnel-type apparatus main body and a conveying means arranged in the apparatus main body, and the object to be frozen / refrigerated conveyed by the conveying means is provided in the apparatus main body. In the refrigeration / refrigeration apparatus that is refrigerated / refrigerated, the apparatus main body is disposed at a position below the conveyance means within the circumferential wall, and a cylindrical peripheral wall that extends in the front-rear direction and surrounds the periphery of the conveyance means. Refrigeration and refrigeration apparatus comprising the evaporator and a cold pressure feeding fan disposed at a side position of the evaporator, and circulating the cold air generated by the evaporator along the inner surface of the peripheral wall by the cold pressure feeding fan Of the inner wall and the inner wall Which are arranged anti-condensation heater between the peripheral wall are known. (For example, refer to Patent Document 1).

As a result, the evaporator is disposed below the conveying means, so that even if foreign matter such as dust or dirt adheres to the evaporator, the foreign matter is conveyed by the conveying means to be frozen and refrigerated. The sanitary environment can be preserved without falling and adhering to an object. Moreover, since the cool air generated by the evaporator can be circulated along the inner surface of the peripheral wall by the cold pressure fan, the cooling efficiency in the peripheral wall can be improved, and the object to be frozen / refrigerated can be effectively Can be frozen and refrigerated. Therefore, the cooling cost can be reduced. In addition, it is possible to reliably prevent the occurrence of condensation, to reliably prevent the propagation of germs, and to better preserve the sanitary environment of the freezing / refrigeration apparatus.
